: Define your parts and assign material properties. For explicit simulations, you often need nonlinear material models, such as Hyperelastic for rubber or Crushable Foam for energy-absorbing components.
: Explicit solvers require a high-quality mesh. A finer mesh is often necessary compared to implicit runs to ensure accurate energy capture. ansys explicit dynamics
where ( L_e ) is the smallest element length and ( c ) is the material sound speed. This is why and mass scaling become critical. : Define your parts and assign material properties
